Six bodies are found in the Colorado Rockies, the young sons of prominent and powerful men. Their ravaged remains replicate the work of a killer thought to have died decades ago and a continent away. FBI agent Dan Molina’s investigation of the murders plunges him into the dark world of the Assemblage, a covenant of sexual predators who traffic in human slaves. For years, this group has stolen children from their beds, bought them from desperately poor parents, and seduced them at bus stations and on the internet. But things are about to change. This time the Assemblage has snatched the wrong child, tempted the wrong fates, and crossed the wrong mother. After decades of searching for her daughter, Hannah Kline, with the help of Agent Molina and the children she has freed, sets out to destroy the men who thought they had buried Hannah and their secrets forever.
